I Application filed January 13,1928. Serial No. 246,579.

This invention appertains to anchors for use on various types of vessels and has for its primary object to provide an anchoring structure of an improved type, wherein a rapid and '5 and positive engagement with the ocean floor and extending through the central portion thereof, from which the arms extend on a line with the diametrical center of the fluke from the end of the greatest width, to provide a shank. I

Another object of the invention is the provision of a ships anchor comprising a hollow frustum member having a knife edge at its inner end with an axially disposed shankconnected with the member, the frustum'shaped member constituting an effective means for engaging in the ground when pull is exerted upon the cable connected with the shank, the body cutting its waydeeper into the ocean floor or water bed upon continued pull there- Another salient feature of the invention is the provision of a plurality ofarms for forming the shank of the anchor-and novel means for connecting the arms with the frustum member, the arms being flattened adjacent to the body to facilitate the cutting or the pass ing of the arms through the ocean floor.

A further object of the invention is the provision of an anchor embodying a hollow frustum member so constructed and arranged as to prevent the chokingof the anchor, when the same is in use. 3

A further object of the invention is to provide an anchor which will effectively prevent dragging and which is of a comparatively small Weight when considered with the common type of anchors n'ow'in use.

A still further object of the invention is to provide an improved ships anchor of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

The invention will be best understood from a'consideration of the following detail de-v is the invention is not confined to any strict conattaching arms formed thereon.

formity with the showing of the drawings but maybe changed or modified as long as such change or modifications are no material departure from the salient features of the invention as expressed in the appendedclaims. In the drawings: p Figure l is a perspective view ofthe improved anchor showin the fluke partly. broken away and in section, Figure 2 is a longitudinal section the anchortaken on the line 2+2 of Figure 3 is a section through the anchor taken on the line 33 of Figure 2 looking in the direction of the arrows, A Figure 4 is a bottom plan view of the an-' chor,

Figure 6 is a detail perspective viewiillustrating a through Figure 7 is a detail perspective view of the companion portion of the shank shown in'Figure 6,and I r Figure 8 is a side elevation of the upper end of the completed shank.

Referring now to the drawings in. detail, -where1n like numerals of reference indicate cor-responding parts throughout, the letter A generally lndicates the improved ships anchor which comprises a frustum member 10 "to-conical shape with its smallest end lowermost, but it is to be understood that this member may. be of any desired hollow frustum It isalso preferredthat the angle of S r the-flukebe arranged at a thirty degree angle to the'axis thereof, so as to prevent choking of the anchor when it is in use, but this can also be modified under certain conditions. The

upper or inner end of the fluke,which isthe end of greatest diameter, is sharpened as at 11, so

portion of theshank with one of the v that the fluke will readily bite into the ocean floor or water bed, as will be later described.

The shank of the anchor, which is indicated generally by the reference character 15 comprises three bar members 16, 17 and 18 which are arranged in side by side relation as shown. The bars are all preferably Welded or otherwise firmly secured together and the arms 16 and 17 can be formed from a single bar of metal'and bent intermediate their ends in par allel relation, the connecting portion being iorn'ied to provide an eye 19 for receiving the chain or anchor cable. The upper end of the arm 18 is provided with a hook which is eX- tended through the eye 19 and terminates in abutting contact with the arms 16 and .17.

This effectively forms a strong and durable shank of great tensile strength.

The inner ends of the bars 16, 17 and 18 have formed thereon arms 21, 22 and 23 respectively, which form an important feature oi the present invention. These arms 21, 22 and 23 are flattened and turn outwardly as at 2st away from the shank toward the lower peripheral edge of the fluke 10. The extreme outer ends of the arms are twisted and have formed thereon attaching feet 25, which can be riveted or otherwise secured to the outer face ot the fluke 10. These attaching feet 25 serve the dual function of securing-the arms in position and also or bracing and strengthening the fluke 10. It is to be noted that the arms are located substantially within the upper and lower edges of the fluke and that the arms do not curve away from the shank until the entrance of the shank into the axial 7 center of the fluke.

From the foregoing description, it will be seen that the shank portion 15 extends from and parallel with thelongitudinal axis of the fluke 10 from the side of greatest diameter and curved inner arms 21, 22 and 28 v are so flattened that the sharp or narrow edges thereof will be directed in the direction of movement of the anchor. In this-manner the progress of movement of the anchor into the earth will not be impeded and the same.

can be readily pulled from position,vwhen the anchor is lifted.

In use of the anchor, pull will be exerted on the shank by the ships cable parallel with or at an angle to the ocean floor or water bed which will cause the fluke to bite into the earth. The harder the pull, the more firmly the anchor will be embedded in the earth. However upon an upward pull on the anchor,- such is exerted when the anchor is to be raised, the flukewill readily disengage itself from the earth and permit the ready lifting thcrcoi. Owing to the shape of the fluke, the same will not choke and thus the entire anchor can be readily lifted.

Changes in details maybe made without departing from the spirit or scope of this invention, but

Having thusdescribed my invention, what I claim as new is:

1. A ships anchor comprising a hollow trustum member open at each end and constituting a fluke, a shank arranged upon and parallel with the axial center of the fluke from that side of greatest diameter comprising a bar bent back upon itself in abutting parallel relation, the connectingportion of said bar constituting a cable attaching eye, a second bar secured to the first bar, a hooked upper end on said last mentioned bar positioned through said eye, and curvedflat arms formed on the inner ends oi'said bars extending toward the lower peripheral edge of the fluke, and attaching feet formed on the outer ends of said arms and connected with said fluke.

2. Ina ships anchor, a fluke comprising a hollow frustum body of sheet metal having the edge of the side of greatest'diameter sharpened, a shank comprising a plurality of bars secured together in side by side relationcand extending axially of the fluke body,the inner ends of said bars being curved to extendradially from the central portion of thefluke to the wall thereof, means for securing the ends of the curved portions of the bars to the wall of the fluke, and a ring member formed at the outer end of the shank constituting a cable receiving eye.

3. In a ships anchor, a fluke comprising a iollow frustum body having the edge of the side of greatest diameter sharpened,a shank comprising a plurality of bars secured to-' gether in side by side relation and extending In testimony whereof Iaflix my signature.
